clean up .o# and .po# files?

[ follow-up to gh-285 ]

Relevant excerpts:

@callistosp:

There are also files produced after every run with the extension .o# and .po# where the # is the number assigned by the grid.

@kyleam:

With gh-306, I focused just on the WK_* files. What to do in terms of cleaning the .o# (should always have output, I think) and .po# (in bbi context, perhaps just has output if parallel environment setup fails, not sure) files seems less clear-cut to me. Either way, I think it makes sense to do separately from gh-306.

@seth127:

I would lean towards just opening a fresh one to consider what to do with the .o# and .po# files. Those contain output from the process running on the grid, and deserve some more investigation and probably discussion before making any moves on cleaning them up.
